HPSD E70 is able to play a delicate and high-resolution sound that is differentiated from previous technologies, because we have invented the Magneto-Static Driver which has an innovative vibration structure that did not exist before.

Exquisite and delicate high-precision

High-end sound E70

The key to EARBRIDGE sound playback technology is to share

the real sense of the Scene as it is.

MagnetoStatic Driver’s surprisingly thin and light diaphragm called Radial Wings Membrane helps the earphones deliver more nature, detailed and accurate sound through its radial, wing-like structure in the middle.

When electrical energy is delivered to MagnetoStatic Hybrid Driver, the MagnetoStatic Driver’s Radial Wings Membrane vibrates in very high speed reproducing detailed and accurate sounds. And, what’s penetrating through those sounds are the deep and rich lows generated by the Twin Magnet System Deep Bass Driver.

As the Hybrid Driver applied to E70 emits sound to the same same axis and the sound sources of the two speakers are very close, the low-range and high-range sound naturally blend without any interruption of phase, allowing a wide range of sounds to be played precisely and harmoniously.

The Electro-static Earphone which has the technology of high resolution, is powered by an electrostatic force and is operated by an auxiliary amplifier, which seems to be inconvenient to carry.

But, E70 is powered by a Magneto-Static force and is operated by the output of portable audio without the need for an auxiliary amplifier, making it easy to carry.

If you have chosen E70 to listen to high-resolution sound, you no longer need to purchase or carry a separate auxiliary amplifier.

The electro-static speaker is a capacity reactance, and the EARBRIDGE magnetic static speaker is a inductive reactance.

Electrostatic systems have high impedance at low frequency Preventive measures are needed because the efficiency is low, high voltage bias circuits are needed, and negative distortion, loss and noise may occur. Increasing voltage or reducing the gap between vibration plates increases efficiency, and controlling the compliance can expand the bass, but be careful that the vibration plate is damaged by the discharge.

The magneto-static speaker of the EARBRIDGE is low impedance, efficient, and magnetic force is used as a bias, so it operates at low voltage and does not require a separate boost circuit.

The 70 package offers a wire strap with permanent magnets. Wire straps are easier to use when wrapping earphone wires, attaching them to refrigerators, whiteboards, or collars, or adjusting wire lengths.

We hope that you will find it more pleasant with this new configuration that was not available in existing earphones.

The E70 package includes the Indigo Limited Edition Pelican case.

The inside of the pelican case contains a specially tailored buffer for the E70, and it is very hard and waterproof, so it will keep the product safer for a longer period of time

There are a lot of people in the world who make earphones and headphones. And they all try their best to reproduce the best sound. 

We are also one of them who are deeply in love with sound and are committed to producing the best sound that is closest to the original sound.

We started this project in a small room located in Incheon, Korea.

We had always wanted a more evolved new structure, and in the end we were able to approach the unique method of making an ultra-thin and light diaphragm to self-operate.

We named this new technology as Magneto-Static, and after spending 1,500 days of planning, designing and having the theory, structure, sound quality and mass production verified, we could finally release this technology to you.

The Magneto-Static technology is operated with low power, which allows to play delicate sound, and the earphones applied with this technology have the features that allows you to assemble and disassemble yourself.

From now on, we are trying to offer you a premium earphone that is excellent in playing live music

We hope that our E70, the earphones we created can play the best sound that will satisfy you.

We also hope you will sincerely support the E70, the outcome of our sincere effort.
